Business_AccountQ: Fix Bug? Tier 4 Studio Voices unusable because of "high-pitched whistling sounds" between syllables
Can team Unmixr help troubleshoot high‑pitched whistling in Tier 4 Studio Voices?
"Tier 4" "Studio Voices" have "high-pitched whistling sounds" between syllables.
Words are pronounced fine ... except "high-pitched whistling sounds" are added between most syllables. It is a "whistling" or "squeaky wheel" and ruins every TTS recording.
This makes "Tier 4" "Studio Voices" utterly unusable, because of added "whistling sounds" -- and these high-pitched sounds give an ear-piercing headache after a few minutes.
I tested most Tier 4 Studio female voices, and every tested voice had the same "Whistling noise" problem.
If Unmixr fixed their "Tier 4 Studio Voices" and removed the added "high-pitched whistling sounds" between syllables... Unmixr would be 5-Stars.
Until then, I can't use it.
Can this "bug" be fixed?

Just adding that i've been experiencing this as well with the T4 studio voices (which are great otherwise!).

same here, is this getting solved?
Yes, it will be solved. We are working on this. As you know, fixing models takes time.
